- The chemical ageing of squalene when in the form of aerosols was considered. Squalene is a natural compound found in animal and plant oils. Through application of optical trapping techniques applied simultaneously with Mie spectroscopy, the refractive index and diameter of the levitated aerosols could be determined. The squalene aerosols were exposed to ozone and oxygen, and the change in the aerosol's refractive index and diameter studied by continuously collecting Mie spectra throughout the exposure. The study observed a decrease in droplet size, increase in density and solidification during the oxidative process.
